How to Fix Outlook Cannot Synchronize Subscribed Folders Error?

By Deepak Singh Bisht

Do you use Microsoft Outlook for your emails and have recently encountered an error message that reads " (0x800CCC0E): Outlook cannot synchronize subscribed folders error"? You're not alone. This issue often occurs for those using IMAP accounts and can be quite frustrating. But, there's no need to worry! In this post, we'll discuss some simple steps to fix this error.

Why This Error Occurs: A Deeper Dive

In Microsoft Outlook, particularly when using an IMAP account, the folders that regularly sync with your email server are known as 'subscribed folders'. This feature is quite handy as it keeps your local copy of the mailbox up-to-date with its server counterpart. However, occasionally Outlook throws a 'cannot synchronize subscribed folders' error when this process is disrupted. Let's explore why this happens in depth:

Unstable Internet Connection: When your internet connectivity is unreliable, Outlook's constant syncing with the server can suffer, resulting in the error.

Firewall and Outlook: Firewalls are designed to protect your system. However, sometimes, they may misidentify Outlook's synchronization as a threat, causing this error.

Antivirus Software Interference: Antivirus software, like firewalls, is created to protect your system, but they may sometimes conflict with Outlook's operations, especially the email protection feature.

Mail Server-IMAP Settings Conflict: If your mail server doesn't recognize the IMAP settings, it can disrupt the synchronization process of the subscribed folder.

But don't worry - we're here with an array of troubleshooting methods that will help you resolve this issue effectively.

Method 1: Verify Your Internet Connection

The internet is essential for email communication. Without a stable connection, Outlook's syncing process can't function properly, leading to the error. Therefore, your first step should be to check your internet connection and ensure its stability.

Method 2: Interact with Your Firewall

If the error persists, your firewall may be obstructing Outlook's syncing process. Temporarily disabling it can help you identify if it's the cause of the problem. However, remember to enable it again once you're done to maintain your system's security.

Method 3: Scrutinize Your Antivirus Software

Antivirus software, in its quest to protect your system, can sometimes interfere with regular programs like Outlook. Temporarily disabling the email protection feature in your antivirus software will help determine if it's causing the error.

Method 4: Remove and Re-add the Email Account

If the strategies above don't help, you may need to consider removing and then re-adding your email account. This method has been known to resolve the error for many users. But remember, it's crucial to back up your data before you remove your email account to avoid potential data loss.

Step 1: Remove the Email Account

  1. Open MS Outlook.
  2. Go to the File menu.
  3. Click on Account settings and select Account settings.
  4. Select the email account you want to remove and click the remove icon.
  5. From the Account Settings popup, click on the Yes button to confirm.

Step 2: Add Email Account

  1. Open MS Outlook.
  2. Go to the File menu and click on the Add Account button.
  3. Enter your name, email, password, and retype the password.
  4. Click on Next to proceed.
  5. Once the account is configured properly, click on the Finish button.

Method 5: Perform a Clean Boot

If none of the methods above work, performing a clean boot may help. A Clean Boot is similar to opening Windows in Safe Mode with fewer drivers and startup programs. This helps you understand if any other program is interfering with Outlook. Here's how you can do it:

  1. Open your system as an administrator.
  2. Type msconfig in the search bar and select System Configuration.
  3. From the System Configuration window, select the Services tab.
  4. Select the Hide all Microsoft services checkbox, and then click on the Disable All button.
  5. From the System Configuration window, select the Startup tab and select Open Task Manager.
  6. Now select every item in the Task Manager and click on the Disable button.
  7. Close Task Manager and restart your system.
  8. Open MS Outlook and add the email account again.

By following these methods, you should be able to rectify the "(0x800CCC0E): Outlook cannot synchronize subscribed folders" error.
